Problem trying to automate decrypt option

[Gabi]

Thanks but both of them does not work, the dialog is ever shown, using
gpg2.exe or gpg.exe.

If I write gpg2.exe --help (or gpg.exe --help) the command or option
--passphrase is not shown anywhere.
I'm using windows version. Is that a feature not available in windows
version?

(And yes storing in a task is a bad idea, is not the final solution, but
only a way to automate a process we'll do in another way but meanwhile...)

Regards.

Have you tried --passphrase "myPassword" or --passphrase-fd 0 (with the
pipe)?

(Standard statement about how storing the passphrase in a scheduled
task is a bad idea, etc.)
